Spiral Model The spiral model, developed by Dr. Barry Boehm6at TRW, is an enhancement of the waterfall/rapid prototype model, with risk analysis preceding each phase of the cascade. You can imagine the rapid prototyping model drawn in the form of a spiral, This model has been successfully used for the internal development of large systems and is especially useful when software reuse is a goal and when specific quality objectives can be incorporated. It does depend on being ableto accurately assess risks during development. This depends on controlling all factors and eliminating or at least minimizing exogenous influences. Like the other extensions of and improvements to the waterfall model, it adds feedback to earlier stages.
